Dortmund by local public transport (recommended)
Take the S1 (every twenty minutes from Dortmund main station) and get off at the stop “Dortmund Universität”. Exit the station and do not walk up the stairs, but instead go to the street ("Vogelpothsweg") by passing the central library (large brown building) on your right. Once you are at the street, turn right and walk straight ahead for about 250 metres until you are at the intersection. Cross the street by turning left onto Emil-Figge-Straße. After about 200 metres, you can find the IBZ (red building) on your right.

Dortmund by car
The TU Dortmund campus is situated between the “Dorstfeld” and “Barop/University” motorway exits, close to the intersection where the A 45 (Frankfurt Dortmund) crosses the A40/B1. The best motorway exit on the B 1 /A40 is “Dortmund-Barop.” There are signs at both exits leading to the university. There are several parking options: either opposite Emil-Figge-Str. 50 (Einfahrt E16 & E18 ), or at Vogelpothsweg underneath the Mensa (Einfahrt E21 & E24).
